The Clean Car Calculator

Until now shopping for a high fuel efficiency car, like an electric or hybrid vehicle, could be confusing with overwhelming amounts of data to digest and compare, but students at The Bren School of Environmental Science and Management at The University of California, Santa Barbara have just made it seductively simple.

Enter the Clean Car Calculator: an elegant online calculator that allows the consumer to compare any two high fuel efficiency vehicles on the market, providing a financial and environmental analysis of the cars and even recommending other vehicles to consider given the user’s criteria. The calculator allows the user to adjust for as many or as few variables as desired, like the car’s primary use, percentage of highway miles driven, government tax incentives, etc. One of the most valuable aspects of the calculator is that it determines how long one must own a high fuel efficiency vehicle for it to make economic sense in fuel savings.

The idea for the calculator was inspired by a homework assignment. Project manager Kate Ziemba explains:

The Calculator resulted from an assignment in the Energy and Resource Productivity class taught by Dr. Sangwon Suh at the Bren School that challenged students to understand the return on investment for businesses and consumers to implement energy saving technologies. Students compared lifetime costs and emissions of conventional gas versus high efficiency vehicles. The graduate student developers were surprised to find that hybrids not only paid themselves back in fuel savings, but also that newly released vehicles, such as the Volt and the Leaf, were smart purchases even without a government subsidy.

There you have it! There is more data everyday to show that electric cars and hybrids make sense for the environment and the consumer. But don’t take our word for it - check out the calculator and have fun comparing a few of your favorite green dream cars.
